North Korea fired a ballistic missile in its first provocation since U.S. President Donald Trump labeled the country a state sponsor of terrorism earlier this month, Yonhap reported, citing South Korea's Joint Chiefs of Staff.

The agency didn't immediately provide more details on the launch. Japan's coast guard said the missile fell into the sea near Japan.

North Korea conducted its sixth and most powerful nuclear test on Sept. 3, and has launched more than a dozen missiles this year as Kim Jong Un's regime seeks the capability to hit the continental U.S. with a nuclear weapon. The United Nations has imposed stringent sanctions on North Korea for its weapons tests.
